Answer: A. Different emotional states affect people’s honesty.
This excerpt states that when people experience different emotional states, their levels of honesty fluctuate too. When people are anxious, stressed out due to the expectations of others, or angry, they are more likely to be dishonest. Therefore, theft and other similar behaviours increase around holidays that rely on these feelings, such as Christmas and Valentine's Day. However, when people are more cheerful and relaxed, dishonest behaviour becomes less common.
